Conor Shaughnessy struck late on as Portsmouth secured the League One title and promotion to the Championship with a 3-2 win over Barnsley at Fratton Park.

Pompey knew one point would return them to the second tier following a 12-year absence, but they were up against it after Devante Cole and John McAtee scored for the play-off chasing Tykes either side of Kusini Yengi’s equaliser.

However, the hosts got the job done courtesy of Colby Bishop’s 83rd-minute penalty and Shaughnessy’s last-gasp effort.

John Mousinho hailed a player he dropped for helping Portsmouth take another big step towards the Championship with a 1-0 win at Peterborough.

The Pompey chief left out two-goal midweek hero Kusini Yengi for a crunch clash at promotion rivals Peterborough.

But the Australian ace responded by climbing off the bench to grab the only goal that kept Portsmouth five points clear at the summit.

Yengi, sent on after Christian Saydee limped off in the first half, raced on to a pass from fellow substitute Gavin Whyte in the 77th minute to fire past Posh keeper Jed Steer.

Peterborough still look bound for the play-offs despite their five-match winning streak coming to an end.

Top-scorer Ephron Mason-Clark blasted against the bar midway through the first half as they drew a blank for just the third time all season in League One.

“I really feel for him,” said Mousinho about match-winner Yengi. “It wasn’t an easy decision to leave him out.

“He scored twice on Tuesday night and his overall performance was really good.

“He has been excellent whenever he has played and his goalscoring record is superb.

“It could have been a difficult one to take, but he was really professional about it when told yesterday. He trained really well in the afternoon, stayed positive around the place and thoroughly deserved his goal.

“At this stage of the season it is all about winning games, but it was a really good performance from us as well.

“The fans made it a special day. That was probably the best away atmosphere I’ve ever experienced.

“To be able to win the game and put in that performance was superb. It was pure relief at the final whistle.

“We’ve just got to keep our heads down and keep winning as many games as possible.”

Posh boss Darren Ferguson said: “I’m really disappointed with the result, but really proud of the performance.

“We were by far the better team on the day and they’re really lucky to come away with a win.

“If anyone from Portsmouth says otherwise, they are kidding themselves.

“We controlled large parts of the game. Some of the play was fantastic.

“But football can be a cruel game and we just couldn’t get that first goal.

“You always need that bit of luck in big games, but we didn’t have it when Ephron hit the underside of the bar.

“I’m gutted for the players as they didn’t deserve to lose the game. You’d rather win and have a bad performance like on Wednesday.

“But if we play like that in the last eight games, we’ll be fine. I’ve still got a lot of confidence that we’re in a good place.

“The break has come at a good time to freshen up for a last push.”

Portsmouth took another big step towards the League One title with a vital 1-0 victory at promotion rivals Peterborough.

Australian striker Kusini Yengi climbed off the bench to grab the only goal in the 77th minute to send an army of 4,000 Pompey fans wild.

Yengi slammed his seventh of the season past Posh keeper Jed Steer to complete a ruthless breakaway after being picked out by fellow substitute Gavin Whyte’s pass.

And that was enough to extend the table-toppers’ unbeaten run to 12 games while bringing Posh’s five-match winning streak to an end.

Captain Harrison Burrows was inches away from giving Posh a first-half lead when steering a low shot past the far post.

Top-scorer Ephron Mason-Clark came even closer to breaking the deadlock when blasting against the bar.

That was soon followed by the best Pompey opportunity of the opening period as Colby Bishop headed a Marlon Pack free-kick straight at Steer.

Malik Mothersille saw a volley fly across the face of goal as Posh started the second half well, but it was Pompey who eventually made the breakthrough to move nine points clear of third place and closer to a Championship return.

Portsmouth manager John Mousinho praised two-goal hero Kusini Yengi after a 2-1 win over Burton retained their lead at the top of League One.

The victory moved leaders Pompey five points clear of second-placed Derby and six in front of Bolton in third.

Mousinho said: “It was a good result. It would be a shame to dwell on the last 10 minutes, because I thought we were excellent in those previous 80 minutes.

“But I said to the players at the end that we need to put games to bed because not doing so allowed them back into the game. Burton changed their shape and personnel which caused us problems at the end.

“We changed shape tonight because of player availability, and I thought it worked well with some good football. We played Kusini because we have options up front, and Colby Bishop has had a heavy workload.

“And, like tonight, he can score goals.”

Albion had the first effort at goal, with Rekeem Harper rattling the Pompey bar in the first minute.

Pompey found life difficult in the final third, but had a superb chance after 37 minutes when Yengi somehow shot wide of an open goal from two yards.

But he made amends in added time, when after having been brought down in the area, got up to score the penalty.

Pompey kept the pressure on in the second half, and despite Abu Kamara blasting high over the bar in the 57th minute, Yengi scored his second six minutes later when he tapped in from a hard low Kamara cross.

Burton pulled one back after 80 minutes when captain John Brayford fired home.

Albion boss Martin Paterson said: “We played a very good team tonight. One that can find holes in defences, so the team did tremendously well.

“My etiquette has always been to not discuss officials, but tonight that changes. The equilibrium of decisions and actions against my football club was not the same as theirs.

“I respect the decision for their penalty, but when my players put in the kind of effort they have tonight, and have an even better penalty shout turned down, it’s difficult not to say something.

“In the second half we made substitutions, changed shape, and scored a good goal.

“It’s totally unfair to my players not to have got a point out of the game. I was really proud of them tonight. We had them on the rack in the last 10 minutes, and the last two games we have been excellent.

“I think we will kick on from this having been denied.”

Kusini Yengi’s double saw Portsmouth take another step closer to the Championship with a 2-1 win against Burton.

The victory moved leaders Pompey five points clear of second-placed Derby and six in front of Bolton in third.

Although Pompey dominated most of the first half, Burton had opportunities without troubling Will Norris.

Burton pulled one back after 80 minutes when captain John Brayford fired home.

A first goal of the season from Myles Peart-Harris helped Portsmouth maintain top spot with a 3-1 win over Cambridge.

The opening half-hour saw Pompey dominate, but Cambridge’s confidence grew and they were rewarded with the opener after 38 minutes.

A corner was headed goalwards by Danny Andrew, and Will Norris could not keep the ball out.

That seemed to spring Pompey into life, and within six minutes the hosts had equalised.

Kusini Yengi was brought down in the box, but he dusted himself down to send the goalkeeper the wrong way.

Cambridge started out the better side in the second half, with Pompey struggling to get any fluency.

But after 59 minutes, they found their spark and went ahead.

Good build-up play saw Peart-Harris slide in to score from a Paddy Lane cross.

Cambridge pushed hard for an equaliser, but Pompey got a third after 71 minutes when Abu Kamara smashed home via the crossbar.

Portsmouth boss John Mousinho saluted Australian striker Kusini Yengi after he helped fire the south coast side to a six-point lead at the top of the League One table as they beat second-placed Bolton 2-0.

Conor Shaughnessy was also on target as Pompey recorded a statement victory at Fratton Park.

Mousinho said: “It was a great result. We were a constant threat going forward.

“I can’t remember our goalkeeper having to deal with anything in the second half. I thought we were comfortable and pushed well.

“We had opportunity after opportunity and were perhaps a bit sloppy in the final third, but when we did get it right, we scored.

“Kusini’s performance against (Ricardo) Santos, who is one of the best centre-halves in the league, was terrific.

“We wanted him to lead the line, and he handled it superbly. He was pressing Santos and the goalkeeper, and we did at the back end of the game wonder if we needed to freshen things up a bit.

“But he showed how fit he is. It was his second league start, and his first here. It was a battle that I thought the referee handled pretty well.

“We’ll savour the moment, then turn the focus to the next game.”

In a fiercely-contested first half, Bolton should have taken the lead after 28 minutes. A powerful header by Jon Dadi Bodvarsson was brilliantly pushed away by Will Norris, and from six yards out and with an open goal, Dion Charles somehow fired the rebound wide.

Pompey then had the ball cleared off the line as Yengi’s shot was partly blocked by goalkeeper Nathan Baxter and Gethin Jones hooked it away.

Right on half-time a corner kick by Jack Sparkes was met by Shaughnessy to glance his header into the net.

Pompey controlled the second half and deserved their second goal a minute from time as Yengi hammered home from six yards from a Gavin Whyte cross.

Bolton boss Ian Evatt said: “I think that in the first half we managed to wrestle control of the game but misses like the one from Dion seemed to affect the flow of our game.

“It’s always frustrating when conceding right on half-time. I thought there was a clear foul leading up to the corner and I can’t understand why it’s not given.

“The second half, they put us on our toes and we couldn’t deal with it. We lost faith and belief, we rocked and wobbled, and it was very disappointing. That’s not what we are about. We are so much better than that.

“They made it very difficult for us and basically dominated on everything. I don’t think they outplayed us, but they outfought us. We’ve let ourselves down but the players have always responded when they have to. We’ve lost the game playing their way, not ours.”

John Mousinho says Kusini Yengi is quickly becoming a “fan favourite” as he netted a brace as Portsmouth progressed 3-1 in the Carabao Cup first round.

His double alongside a Zak Swanson strike saw Pompey overcome Sky Bet League Two opponents Forest Green at The Bolt New Lawn.

“He’s quickly becoming a fan favourite and overall I’m really pleased with Kasini, especially his physical presence up front,” said the Pompey boss.

“He probably had four or five good chances, one in the first half which I think he’ll be upset he hasn’t put away, and a brilliant save from his header.

“His work rate, how he held the ball up, and ultimately putting the ball into the back of the net means really good things for him.

Rovers took the lead through Tyrese Omotoye’s first goal for the club but they failed to capitalise on their lead as League One club Pompey replied with three unanswered goals.

Australian forward Yengi bundled home an equaliser following an Anthony Scully corner before the break.

The turnaround was complete as Swanson gave the visitors the lead as he fired past Searle from a tight angle down Pompey’s right side.

Yengi added Pompey’s third from the penalty as Kamara was upended by Rovers full-back Jamie Robson.

Forest Green head coach David Horseman said: “We gave a really strong League One team a good game, we managed to look at some players we haven’t seen in the building yet.

“The goals were really soft, but we’ll pick those up. For 60 minutes, we looked a really good team.

“There’s a lot to work with and hopefully people around the ground notice how much progress we’re making in such a short space of time.

“I’m pleased for Tyrese because he’s put in a lot of work but things aren’t quite going for us at the moment.”

Kusini Yengi made it three goals in four days as he guided Portsmouth to a comeback 3-1 win against Forest Green in the Carabao Cup’s first round.

His brace, coupled with a Zak Swanson strike, saw Pompey overcome their Sky Bet League Two opponents at The Bolt New Lawn.

Tyrese Omotoye scored his first goal for Forest Green to open his account for Rovers.

Rovers stopper Jamie Searle had to react quickly to repel Yengi’s fine downward header from an Anthony Scully header early on.

Rovers took the lead with a fine strike by Omotoye, found by Teddy Jenks before the forward produced a crisp drive past Pompey goalkeeper Ryan Schofield.

Portsmouth’s set-piece link-up play worked the second time around for Pompey as Scully’s deep corner was bundled home by Yengi after Searle failed to collect the cross.

The turnaround was complete as Swanson gave the visitors the lead as he fired past Searle from a tight angle down Pompey’s right side.

Harvey Bunker drilled an effort towards Schofield’s top corner but the Pompey man was up to the task in Rovers’ best moment after the break.

Yengi added a third from the spot after Kamara was upended by Rovers full-back Jamie Robson in the penalty area.

A dramatic added-time equaliser from debutant Kusini Yengi saw Portsmouth grab a 1-1 draw against Bristol Rovers at Fratton Park.

Luke Thomas had put Rovers ahead in the first half and it appeared they were heading for an opening day victory in League One before Yengi’s late strike.

The enthusiastic welcome the players received was not matched by either side in the opening period, with constant downpours making the pitch difficult to play on.

Rovers forced the early pressure and took the lead in the 24th minute. A quick break saw Jevani Brown go clear on the left and a low cross fell to the feet of Thomas, who confidently drove home.

Pompey produced two good efforts from Colby Bishop and Gavin Whyte as they pressed for an equaliser.

The second half saw Pompey coming out all guns blazing and the same pair again caused problems. Whyte had a stunning strike pushed over by Matthew Cox within the first two minutes followed quicky by a Bishop header that missed the target.

It appeared Rovers were going to hold on but Yengi headed home the equaliser two minutes into added time.
